DRYING-OIL.

SPECIFICATION forming part of Letters Patent No. 767,682, dated August 16, 1904.

Application filed August 11, 1903. Serial No. 169,095. (No specimens.)

To rtZZ whom it may concern.-

Be it known that 1, WILLIAM N. BLAKEMAN, Jr. of the borough of Manhattan, in the city, county, and State of New York, have invented a new and useful Drying-Oil, which invention is' fully set forth in the following specification.

The object of this invention is to treat nondrying fatty oils in such a manner that drying properties will be imparted thereto, thus rendering them available for use for many purposes for which they are not now adapted.

The non-drying fatty oils which may be treated by my process are cotton-oil, sunflower-oil, corn-oil, castor-oil, and thelike; and my invention consists in incorporating with such oils a small percentage of tung-oil, known also as Chinese or J apanese wood-oil.

Tung-oil seems to be a very remarkable oleaginous product, the composition of which is not now well understood, and although classed among the drying-oils the result of its induration is very different from the oxidized film of the well-known drying-oils, for when exposed to the atmosphere in a thin layer on plain surfaces it dries to a rough, opaque, and arborescent film.

I have discovered that when about fifteen per cent. of tung-oil is incorporated with one of the non-drying fatty oilscotton-oil, for examplethe compound or mixture will form a drying-oil possessing good drying qualities well adapted for use in the arts for many purposes.

In carrying out my process I simply take the desired proportions of each oil and thoroughly incorporate one with the other. Either the tung-oil or the non-drying fatty oil, or. both, may be oxidized before being combined, and a more energetic and complete blending thus effected.

The tung-oil may be combined with a mixture of two or more of the non-drying oils. From five to ten per cent. of linseed or other drying oil, either raw or boiled, may be added as a drier, if desired, in which case the proportion of tung-oil may be slightly reduced.

The proportion of tung-oil which I use is from about ten per cent. as a minimum to twenty-five per cent. as a maximum, depending upon the nature of the non-drying oil used, fifteen per cent. giving satisfactory results in nearly every case.

In another application, Serial No. 169,096, filed herewith,I have claimed a paint compound made from the drying-oil herein described, in combination with a pigment.

Having thus fully described my invention, I claim I 1. As a new composition of matter, a drying-oil composed of, substantially, eighty-five parts of non-drying fatty oil and fifteen parts of tung-oil.

2. As a new composition of matter, a drying-oil composed of, substantially, eighty-five parts of cotton-oil and fifteen parts of tungoil.

3. As a new composition of matter, a drying-oil composed of tung-oil and an oxidized non-drying fatty oil.

4:. As a new composition of matter, a drying-oil, composed of oxidized tung-oil and an oxidized non-drying fatty oil.

5. As a new composition of matter, a drying-oil composed of, substantially, eighty-five parts of non-drying fatty oil, fifteen parts of tung-oil, and a drier.
